Blue and White Swallow Photograph by Robert Scanlon The upperparts are a glossy blue while the wings and tail are black. The underparts are white from the throat downwards and the undertail coverts are black. the tail is slightly forked. The immature are brown above with pinkish brown on the throat and darker brown on the chest. The adult size is 4.7 inches (12 cm) and the weight is 10.5 grams. The White-winged Swallow is
very similar to the Blue and White Swallow. A key difference is the white wing patch
evident on the folded wings of the White-winged Swallow but absent in Blue and White
Swallow. If viewed from below the white wing patch looks like a thin white line on the
bend of the wing. Additionally, the Blue and White Swallow shows a contrast between white
breast and belly and dark gray ventral area, whilst White-winged Swallows are concolourous
underneath. Family - Swallow Latin Name - Notiochelidon cyanoleuca Range - Mexico south to South America covering Panama, Colombia, Venezuela, Trinidad and the Guianas. Photograph by Peter Price
